I did the 12-Bolt Swap. The advantage for me was that I went from a 4.30 to a 4.56 ratio because I did the front third and the rear end and I got disk brakes in the rear. I wouldn't really call this a drop in swap though. As Jim mentioned, I had to play around with the E-Brake cables. You will also want to find a rear end with matching tone ring. Otherwise your Rear ABS will be disabled. Not that it was really that helpful anyway.

Last but not least I also did the one-peice drive shaft as my carrier bearing went around the same time.
